In some demonstrative embodiments, an aggregated channel may include a primary channel and a secondary channel, e.g., as described below.

In some demonstrative embodiments, a beamforming training, for example, when channel aggregation is used, may implement a BRP Transmit Sector Sweep (TXSS) procedure, e.g., as described below.

In some demonstrative embodiments, there may be a need to address a technical issue of, for example, establishing communication between two STAs over two aggregated channels, for example, including a primary channel of an aggregated channel bandwidth and a secondary channel of an aggregated channel bandwidth. For example, the two STAs may already have a link established in a primary channel, and may have already determined antenna settings for transmission and/or reception in the primary channel, which may enable communications between the two STAs in the primary channel. For example, after intent to use channel aggregation is indicated and acknowledged using the primary channel, the STAs may perform beamforming training in a secondary channel to determine antenna settings for transmission and/or reception in the secondary channel.

In some demonstrative embodiments, beamforming training may be performed using a BRP TXSS protocol, which may include the transmission of BRP frames by both STAs (initiator and responder of the procedure), e.g., in accordance with an IEEE 802.11ay Specification. However, when intent to perform channel aggregation is indicated and acknowledged, the STAs may still have not determined antenna settings for the secondary channel.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive and/or process one or more transmissions of the EDMG BRP packets sent in a secondary aggregated channel, for example, even before communication between devices 102 and/or 140 is established in the secondary channel, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive and/or process BRP frames communicated in the secondary aggregated channel, for example, even before communication between devices 102 and/or 140 is established in the secondary channel, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive and/or process BRP frames over a secondary channel of an aggregated channel bandwidth, for example, even before communication between devices 102 and/or 140 is established in the secondary channel, for example, at a control mode rate or higher Modulation and Coding Scheme (MCS), e.g., as described below.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control a wireless station implemented by device 102, e.g., a first EDMG STA, to exchange first and second BRP setup frames with a wireless station implemented by device 140, e.g., a second EDMG STA, for example, to initiate a BRP TXSS over an aggregated channel bandwidth including an aggregation of a primary channel and a secondary channel in a frequency band above 45 GHz, e.g., as described below.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to determine a transmit beamforming configuration over the aggregated channel bandwidth, for example, based on BRP feedback from device 140, e.g., as described below.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to transmit an EDMG PPDU to device 140 over the aggregated channel bandwidth, for example, based on the transmit beamforming configuration, e.g., as described below.

In some demonstrative embodiments, an AWV antenna setting used for the transmission of BRP frames, for example, including preambles, headers, and/or the data field, in the secondary channel may be chosen by the implementation, for example, when beamforming training is performed for the channel aggregation case before communication in the secondary channel has been established. For example, the AWV antenna setting used for the transmission of one or more subfields of BRP packets over the secondary channel may be chosen by the implementation. In one example, the AWV antenna setting used for the transmission of the first P TRN subfields, for example, in each Training Unit (TRN-Unit), that include the TRN field of EDMG BRP-Transmit (BRP-TX) and/or EDMG BRP-Receive (BRP-RX) packets, for example, used in the beamforming training procedure, may be chosen by the implementation.

In some demonstrative embodiments, device 140 (FIG. 1) may perform a role, one or more functionalities of, one or more operations of, and/or one or more procedures of, a responder 340 of BRP TXSS protocol 300.

As shown in FIG. 3, BRP TXSS protocol 300 may include a setup phase 306, during which initiator 302 may exchange first and second BRP setup frames with responder 340, for example, to initiate BRP TXSS protocol 300 over an aggregated channel bandwidth.

For example, as shown in FIG. 3, initiator 302 may transmit to responder 340 a first BRP setup frame 322, which may be duplicated over a primary channel 303 and a secondary channel 305 of the aggregated channel bandwidth. For example, as shown in FIG. 3, responder 340 may transmit to initiator 302 a second BRP setup frame 324, which may be duplicated over primary channel 303 and secondary channel 305 of the aggregated channel bandwidth.

As shown in FIG. 3, BRP TXSS protocol 300 may include an initiator BRP TXSS phase 308, for example, following setup phase 306.

As shown in FIG. 3, during initiator BRP TXSS phase 308, initiator 302 may to transmit to responder 340 a plurality of BRP frames 326 duplicated over primary channel 303 and secondary channel 305.

For example, initiator 302 may transmit to responder 340 BRP frames 326 during initiator BRP TXSS 308, for example, according to an EDMG control mode.

As shown in FIG. 3, initiator 302 may be configured to receive from responder 340 BRP feedback 328 duplicated over primary channel 303 and secondary channel 305, for example, during initiator BRP TXSS phase 308. For example, BRP feedback 328 may be based on measurements performed at responder 340 based on the BRP frames 326.

In some demonstrative embodiments, initiator 302 may be configured to determine a transmit beamforming configuration over the aggregated channel bandwidth, for example, based on BRP feedback 328 from responder 340.

In some demonstrative embodiments, initiator 302 may be configured to transmit an EDMG PPDU to responder 340 over the aggregated channel bandwidth, for example, based on the transmit beamforming configuration.

As shown in FIG. 3, BRP TXSS protocol 300 may include an acknowledgement stage 312, during which initiator 302 may transmit to responder 340 a BRP acknowledgement frame 330.

As shown in FIG. 3, BRP TXSS protocol 300 may include a responder BRP TXSS phase 310, for example, following initiator BRP TXSS phase 308.

As shown in FIG. 3, during responder BRP TXSS phase 310, responder 340 may transmit to initiator 302 a plurality of BRP frames 332 duplicated over primary channel 303 and secondary channel 305.

For example, responder 340 may transmit to initiator 302 BRP frames 332 during responder BRP TXSS 310, for example, according to an EDMG control mode.

As shown in FIG. 3, responder 340 may be configured to receive from initiator 302 BRP feedback 334 duplicated over primary channel 303 and secondary channel 305, for example, during responder BRP TXSS phase 310. For example, BRP feedback 334 may be based on measurements performed at initiator 302 based on the BRP frames 332.

In some demonstrative embodiments, responder 340 may be configured to determine a transmit beamforming configuration over the aggregated channel bandwidth, for example, based on BRP feedback 334 from initiator 302.

In some demonstrative embodiments, responder 340 may be configured to transmit an EDMG PPDU to initiator 302 over the aggregated channel bandwidth, for example, based on the transmit beamforming configuration.

In some demonstrative embodiments, devices 102 (FIG. 1) and/or 140 (FIG. 1) may communicate EDMG BRP packets, for example, in accordance with BRP TXSS protocol 300. For example, the EDMG BRP packets may include BRP frames with an attached TRN field, e.g., TRN field 224 (FIG. 2).

In some demonstrative embodiments, devices 102 (FIG. 1) and/or 140 (FIG. 1) may communicate the EDMG BRP packets, e.g., BRP packets 326 and/or BRP packets 332, to perform beamforming training over the primary channel and the secondary channel of the aggregated channel bandwidth. For example, a receiver STA of the EDMG BRP packets, e.g., responder 340 receiving BRP frames 326 and/or initiator 302 receiving BRP frames 332, may use the EDMG BRP packets, e.g., BRP frames that have a TRN field attached to them, to perform a beamforming training, for example, even though the sector/AWV used in the transmission of BRP frames in the secondary channel have not been determined yet. For example, the receiver STA may determine the timing of a signal in the secondary channel based on the reception of the signal in the primary channel, e.g., as described below.

Reference is made to FIG. 4, which schematically illustrates an EDMG BRP packet transmission 400, which may be implemented in accordance with some demonstrative embodiments. In one example, devices 102 (FIG. 1) and/or 140 (FIG. 1) may be configured to generate, transmit, receive and/or process one or more EDMG BRP packets according to EDMG BRP packet transmission 400.

In one example, EDMG BRP packet transmission 400 may include a duplicated transmission of a BRP frame 326 (FIG. 3) over a primary channel and a secondary channel of an aggregated channel bandwidth. In another example, EDMG BRP packet transmission 400 may include a duplicated transmission of a BRP frame 332 (FIG. 3) over the primary channel and the secondary channel of the aggregated channel bandwidth.

In some demonstrative embodiments, a receiver STA of EDMG BRP packet transmission 400, e.g., responder 340 receiving BRP frames 326 and/or initiator 302 receiving BRP frames 332, may receive EDMG BRP packet transmission 400, for example, over both the primary channel and the secondary channel of the aggregated channel bandwidth.

As shown in FIG. 4, the receiver STA may be able to determine timing of the signal in the secondary channel, for example, as signals transmitted in aggregated channels may have substantially no time delay between them.

In one example, time delays introduced in the channel are expected to be relatively short, for example, less than the guard interval, and have no significant impact in Signal-to-Noise Ratio (SNR) measurements. Accordingly, the receiver STA may be configured to determine with good accuracy the start of the TRN field, e.g., TRN field 224 (FIG. 2), in the EDMG BRP packet 400 transmitted in the secondary channel, for example, based on the reception of the corresponding frame in the primary channel, and the receiver STA may use the TRN field to perform measurements.

In some demonstrative embodiments, a beamforming training procedure for aggregated channels, for example, including communication of EDMG BRP packet transmission 400, which may be suitable, for example, for implementing even before communication in the secondary channel has been established, may be configured according to one or more of the following requirements:

-   -   The duration of the data field of EDMG BRP packets transmitted         simultaneously in a primary channel and a secondary channel         shall be the same. For example, simultaneous transmission may         include, for example, no time delay or possibly a time delay         that is defined in an IEEE 802.11ay Specification and/or any         other specification. The delay could be defined, for example, in         terms of a fixed value or in a range of values, with the actual         value used possibly chosen by the implementation.     -   The configuration of the TRN field of EDMG BRP packets         transmitted simultaneously in a primary channel and a secondary         channel shall be the same. Specifically, the values of the         fields EDMG TRN Length, RX TRN-Units per Each TX TRN-Unit, EDMG         TRN-Unit P, EDMG TRN-Unit M and/or EDMG TRN-Unit N in the         EDMG-Header-A of both EDMG BRP frames shall be the same.

In other embodiments, a beamforming training procedure for aggregated channels before communication in the secondary channel has been established may be configured according to any other additional and/or alternative requirements.

In some demonstrative embodiments, EDMG STAs, e.g., devices 102 and/or 140 (FIG. 1), may be configured to implement a beamforming training procedure for aggregated channels according to one or more of the requirements of duration of a data field of EDMG BRP packets, and/or requirements for a configuration of the TRN field of EDMG BRP packets, e.g., as described above.

In some demonstrative embodiments, the EDMG STAs, e.g., devices 102 and/or 140 (FIG. 1), may be configured to communicate EDMG BRP packets, for example, according to a protocol, which may restrict the transmission of BRP frames in a BRP TXSS performed over two aggregated channels, e.g., the transmission of BRP frames 326 (FIG. 3) in initiator BRP TXSS 308 (FIG. 3) and/or the transmission of BRP frames 332 (FIG. 3) in responder BRP TXSS 310 (FIG. 3), before communication in the secondary channel has been established, to be made by using the EDMG Control Mode in the non-EDMG duplicate format, for example, in accordance with an IEEE 802.11ay Specification.

In some demonstrative embodiments, the EDMG STAs, e.g., devices 102 and/or 140 (FIG. 1), may be configured to implement a beamforming training procedure for aggregated channels, e.g., before communication in the secondary channel has been established, for example, according to one or more of the following requirements:

-   -   The TRN-Unit RX Pattern field in the EDMG-Header-A of EDMG         BRP-TX packets, e.g., EDMG Header A 208 (FIG. 2), shall be set         to “1”, for example, to indicate that measurements shall be         performed using a quasi-omni antenna pattern.     -   Measurements on the same frames are to be reported in BRP frames         transmitted simultaneously in a primary channel and a secondary         channel. Alternatively, BRP frames used to feedback measurements         shall be transmitted in the primary channel only.     -   The data field of BRP frames used to setup the BRP procedure         that are transmitted simultaneously in a primary channel and a         secondary channel shall be the same. Alternatively, BRP frames         used to setup a BRP procedure in this case shall be transmitted         in the primary channel only.

In other embodiments, any other additional or alternative requirements may be implemented to support a beamforming training procedure for aggregated channels before communication in the secondary channel has been established.

Referring back to FIG. 1, in some demonstrative embodiments, devices 102 and/or 140 may be configured to support and/or implement one or more operations of setting up on a first channel a Sector-Level Sweep (SLS) procedure over a second channel, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to define an SLS procedure for channel aggregation. For example, SLS may not require that a link has already been established, and/or may not assume that the timing of BRP frames transmitted in a channel, for example, a secondary channel of an aggregated channel bandwidth, can be inferred from signals transmitted in a different channel, for example, a primary channel of the aggregated channel bandwidth, e.g., as described below.

In some demonstrative embodiments, the SLS procedure may be implemented to support beamforming training in the secondary channel of the aggregated channel bandwidth, for example, even before a link in the secondary channel is established, e.g., as described below.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to exchange an SLS request and an SLS response with device 140 over a first channel in a frequency band above 45 GHz, e.g., as described below.

In some demonstrative embodiments, the SLS request may include channel information to identify a second channel in the frequency band above 45 GHz, and the SLS response may include an indication whether the SLS request is confirmed, e.g., as described below.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to perform an Initiator Sector Sweep (ISS) of the SLS with device 140 over the second channel, for example, when the SLS request is confirmed, e.g., as described below.

In some demonstrative embodiments, the first channel may include a primary channel of an aggregated channel bandwidth and the second channel may include a secondary channel of the aggregated channel bandwidth, e.g., as described above.

In some demonstrative embodiments, the aggregated channel bandwidth may include a 2.16+2.16 GHz channel bandwidth or a 4.32+4.32 GHz channel bandwidth, e.g., as described below.

In other embodiments, the first channel and the second channel may include any other channels of any other channel bandwidth.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to setup an SLS with device 140 over a secondary channel of an aggregated channel bandwidth, for example, by exchanging with device 140 an SLS request frame and an SLS response frame over a primary channel of the aggregated channel bandwidth, e.g., as described below.

In some demonstrative embodiments, the SLS request may include channel information to identify the secondary channel, and the SLS response may include an indication whether the SLS request is confirmed, e.g., as described below.

In some demonstrative embodiments, the SLS request may include a grant frame and the SLS response may include a grant Acknowledgement (Ack) frame, e.g., as described below.

In other embodiments, the SLS request and/or the SLS response may include any other type of frame.

In some demonstrative embodiments, a control trailer of the grant frame may include a channel number of the secondary channel, e.g. as described below.

In some demonstrative embodiments, a control trailer of the grant Ack frame may include the channel number of the secondary channel, for example, when the SLS request is confirmed, e.g., as described below.

In some demonstrative embodiments, the SLS request may include a timeout value, for example, to indicate a timeout of the SLS request relative to a time indicated by a duration field of the grant frame, e.g., as described below.

In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to perform a role of an initiator of the SLS; and/or controller 154 may be configured to cause, trigger, and/or control the wireless station implemented by device 140 to perform a role of a responder of the SLS, e.g., as described below.

In other embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless station implemented by device 102 to perform a role of a responder of the SLS; and/or controller 154 may be configured to cause, trigger, and/or control the wireless station implemented by device 140 to perform a role of an initiator of the SLS.

In some demonstrative embodiments, the initiator of the SLS, e.g., device 102, may be configured to transmit the SLS request over the primary channel, to receive the SLS response over the primary channel, and to transmit during the ISS one or more Sector Sweep (SSW) frames or short-SSW frames over the secondary channel to a device performing a role of the responder of the SLS, for example, device 140, e.g., as described below.

In some demonstrative embodiments, the responder of the SLS, e.g., device 140, may be configured to receive the SLS request over the primary channel, to transmit the SLS response over the primary channel, and to receive during the ISS one or more SSW frames or short-SSW frames over the secondary channel from a device performing a role of the initiator, for example, device 102, e.g., as described below.

Reference is made to FIG. 5, which schematically illustrates an SLS protocol 500, which may be implemented in accordance with some demonstrative embodiments. In one example, devices 102 (FIG. 1) and/or 140 (FIG. 1) may be configured to perform an SLS procedure for channel aggregation in accordance with SLS protocol 500.

For example, SLS protocol 500 may be configured to support channel aggregation, which may allow performing beamforming training in the secondary channel, for example, even before a link is established in the secondary channel.

In some demonstrative embodiments, device 102 (FIG. 1) may operate as, perform the role of, and/or perform one or more functionalities of, an initiator of SLS protocol 500, and/or device 140 (FIG. 1) may operate as, perform the role of, and/or perform one or more functionalities of, a responder of SLS protocol 500.

In other embodiments, device 140 (FIG. 1) may operate as, perform the role of, and/or perform one or more functionalities of, the initiator of SLS protocol 500, and device 102 (FIG. 1) may operate as, perform the role of, and/or perform one or more functionalities of, the responder of SLS protocol 500.

As shown in FIG. 5, the initiator of SLS protocol 500, e.g., device 102 (FIG. 1), may send an SLS request 510 to the responder, e.g., device 140 (FIG. 1), in a first channel 502, denoted channel A. For example, first channel 502 may include a primary channel of an aggregated channel bandwidth.

For example, SLS request 510 may be in the form of a Grant frame appended with a control trailer that includes an allocation in a second channel 504, denoted channel B, along with some additional information that will be used for the upcoming SLS performed in second channel 504. For example, second channel 504 may include a secondary channel of the aggregated channel bandwidth.

In some demonstrative embodiments, Grant frame 510 may be transmitted in first channel 502, but in the control trailer appended to Grant frame 510, the channel number of second channel 504 may be included so that the responder, e.g., device 140 (FIG. 1), knows the initiator, e.g., device 102 (FIG. 1), is requesting to start an SLS with the responder in the second channel 504.

In some demonstrative embodiments, the initiator, e.g., device 102 (FIG. 1), may include a timeout value, denoted T, in the control trailer appended to Grant frame 510. For example, if neither the initiator nor the responder can communicate with each other on second channel 504 for a time T starting with time D, where D is the value of the Duration field in Grant frame 510, then the initiator and responder may consider the attempt unsuccessful and return to first channel 502.

In some demonstrative embodiments, the responder, e.g., device 140 (FIG. 1), may transmit an acknowledgement frame 512, which may be in the form of a Grant ACK appended with a control trailer.

In some demonstrative embodiments, the initiator, e.g., device 102 (FIG. 1), may start an Initiator Sector Sweep (ISS) 514 in second channel 504, for example, after a pre-defined interval following the transmission of Grant ACK 512. For example, ISS 514 may include an Initiator TXSS, and may make use of either multiple SSW frames or multiple Short SSW frames. For example, ISS 514 may include and/or support one or more procedures and/or operations in accordance with the IEEE 802.11-2016 Standard, and/or an IEEE 802.11ay Specification.

In some demonstrative embodiments, a channel number for second channel 504 may be included, for example, in the appended control trailer of Grant Ack frame 512 from the responder.

In one example, the initiator of SLS protocol 500 may determine that the SLS request in second channel 504 may be confirmed by the responder, and the initiator may start the SLS in second channel 504, for example, if the channel number in the appended control trailer of Grant Ack frame 512 from the responder is equal to the channel number of second channel 504 previously contained in the control trailer appended to Grant frame 510 from the initiator.

In one example, the initiator shall consider an unsuccessful agreement on the SLS and shall not start the SLS in second channel 504, for example, if the channel number in the appended control trailer of Grant Ack frame 512 transmitted by the responder is different from the channel number of second channel 504 previously contained in the control trailer appended to Grant frame 510 from the initiator.

In some demonstrative embodiments, the responder may start a Responder Sector Sweep (RSS) 516 in second channel 504, for example, after a pre-defined interval following the transmission of the last packet transmitted by the initiator in ISS 514. For example, RSS 516 may include a Responder TXSS and may make use of either multiple SSW frames or multiple Short SSW frames. For example, RSS 516 may include one or more procedures and/or operations in accordance with the IEEE 802.11-2016 Standard, and/or an IEEE 802.11ay Specification.

In some demonstrative embodiments, the initiator shall transmit an SSW-Feedback frame 518 to the responder in second channel 504, for example, after a pre-defined interval following the transmission of the last packet transmitted by the responder in RSS 516. For example, the feedback procedure may include one or more procedures and/or operations in accordance with the IEEE 802.11-2016 Standard, and/or an IEEE 802.11ay Specification.

In some demonstrative embodiments, the responder shall transmit an SSW-ACK frame 520 to the initiator in second channel 504 to perform an SSW ACK procedure, for example, after a pre-defined interval following the transmission of SSW-Feedback frame 518. For example, the SSW ACK procedure may include one or more procedures and/or operations in accordance with the IEEE 802.11-2016 Standard, and/or an IEEE 802.11ay Specification.

Referring back to FIG. 1, in some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive and/or process one or more different types of EDMG BRP packets, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive and/or process one or more of the following three types of EDMG BRP packets:

-   -   EDMG BRP-RX for receive training and tracking;     -   EDMG BRP-TX for transmit training and tracking; and/or     -   EDMG BRP-RX/TX for simultaneous receive and transmit training         and tracking.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to perform one or more operations of transmit beam tracking and/or receive beam tracking procedures, for example, in accordance with an IEEE 802.11ay Specification and/or any other Specification.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive and/or process one or more transmissions of the EDMG BRP-RX/TX packets, for example, to support a simultaneous receive and transmit tracking procedure, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more procedures, as well as their required signaling, to enable simultaneous receive and transmit tracking, for example, using EDMG BRP-RX/TX packets, e.g., as described below.

In some demonstrative embodiments, device 102 may operate as, perform the role of, and/or perform one or more functionalities of, an initiator EDMG STA of a beamforming procedure, and/or device 140 may operate as, perform the role of, and/or perform one or more functionalities of, a responder EDMG STA of the beamforming procedure.

In other embodiments, device 140 may operate as, perform the role of, and/or perform one or more functionalities of, the initiator EDMG STA, and/or device 102 may operate as, perform the role of, and/or perform one or more functionalities of, the responder EDMG STA.

For example, in accordance with an IEEE 802.11ay Specification, an initiator EDMG STA, e.g., device 102, may send a request for transmit beam tracking to a responder EDMG STA, e.g., device 140, for example, by setting one or more of the following fields in a transmitted packet:

-   -   The “Packet Type” field in the L-Header equal to 1 and the “RX         TRN-Units per Each TX TRN-Unit” field in the EDMG-Header-A equal         to 0 (to indicate the transmission of an EDMG BRP-TX packet);     -   The “Beam Tracking Request” field in the L-Header equal to 0 and         the “EDMG Beam Tracking Request” field in the EDMG-Header-A         equal to 1 (to indicate a request for beam tracking); and     -   The “EDMG TRN Length” in the EDMG-Header-A equal to the number         of appended TRN-Units to the packet, which shall be greater than         zero.

For example, a beam tracking responder, e.g., device 140, may perform measurements, for example, using the received EDMG BRP-TX packet, and may send feedback to the beam tracking initiator, e.g., device 102.

For example, in accordance with an IEEE 802.11ay Specification, an initiator EDMG STA, e.g., device 102, may send a request for receive beam tracking to a responder EDMG STA, e.g., device 140, for example, by setting one or more of the following fields in a transmitted packet:

-   -   The “Packet Type” field in the L-Header equal to 0 and the “RX         TRN-Units per Each TX TRN-Unit” field in the EDMG-Header-A equal         to 0 (which, together with the configuration below, indicates a         request for the transmission of an EDMG BRP-RX packet);     -   The “Beam Tracking Request” field in the L-Header equal to 0 and         the “EDMG Beam Tracking Request” field in the EDMG-Header-A         equal to 1 (to indicate a request for beam tracking); and     -   The “EDMG TRN Length” in the EDMG-Header-A equal to the number         of requested TRN-Units, which shall be greater than zero.

For example, the beam tracking responder, e.g., device 140, may send an EDMG BRP-RX packet to the beam tracking initiator, e.g., device 102, for example, with the number of TRN-Units requested by the beam tracking initiator appended to the packet.

Some demonstrative embodiments may be configured to utilize a third beam tracking procedure (also referred to as “unsolicited receive beam tracking”), for example, in accordance with an IEEE 802.11ay Specification and/or any other Specification.

For example, according to an unsolicited receive beam tracking procedure, an initiator EDMG STA, e.g., device 102, may send an EDMG BRP-RX packet to a responder EDMG STA, e.g., device 140, for example, with no prior request by the responder EDMG STA, that the responder EDMG STA may use to perform receive beam tracking. For example, a beam tracking initiator, e.g., device 102, may transmit the EDMG BRP-RX packet, e.g., using one or more of the following settings:

-   -   The “Packet Type” field in the L-Header is equal to 0 and the         “RX TRN-Units per Each TX TRN-Unit” field in the EDMG-Header-A         is equal to 0 (which, together with the configuration below,         indicates an EDMG BRP-RX packet);     -   The “Beam Tracking Request” field in the L-Header is equal to 0         and the “EDMG Beam Tracking Request” field in the EDMG-Header-A         is equal to 0 (which, together with the configuration above,         indicates an EDMG BRP-RX packet); and     -   The “EDMG TRN Length” in the EDMG-Header-A is equal to the         number of TRN-Units appended to the packet, which shall be         greater than zero.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to support and/or implement beam tracking procedures, which use EDMG BRP-RX and/or EDMG BRP-TX packets, and allow for either receive beam tracking or transmit beam tracking.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use an EDMG BRP-RX/TX packet, for example, for simultaneous receive and transmit beam tracking, e.g., in accordance with an IEEE 802.11ay Specification and/or any other Specification, e.g., as described below.

In some demonstrative embodiments, there may be a need to provide a definition of how EDMG BRP-RX/TX packets can be used for beam tracking, for example, in a way, which may be unambiguous and/or complete.

For example, it may not be complete to define that “a beam tracking initiator may use procedures specified in an IEEE 802.11ay Specification to request a beam tracking responder to perform both transmit and receive beam tracking on the same packet. This is done by, on top of the corresponding TXVECTOR parameter configuration specified in an IEEE 802.11ay Specification, setting the TXVECTOR parameter RX_TRN_PER_TX_TRN to a value greater than zero and the Packet Type to TRN-T-PACKET. In this case, the beam tracking initiator and beam tracking responder shall use the rules described in 30.9.2.2 of an IEEE 802.11ay Specification to perform both transmit and receive training over the TRN subfields appended to the transmitted packet”.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more operations to support and/or enable one or more receive and/or transmit beam tracking procedures, which may make more efficient use of EDMG BRP-RX/TX packets and/or enable simultaneous receive and transmit tracking, for example, in accordance with an IEEE 802.11ay Specification, e.g., as described below.

3. The beam tracking initiator then sends feedback to the beam tracking responder based on the transmit tracking measurements it made on the EDMG BRP-RX/TX packet sent by the beam tracking responder.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement the simultaneous receive and transmit beam tracking procedure, e.g., using one or more of the following operations:

1. An EDMG STA (initiator) requests receive beam tracking to a peer EDMG STA (responder) by setting the following fields in a transmitted packet:

-   -   a) The “Packet Type” field in the L-Header equal to 0 and the         “RX TRN-Units per Each TX TRN-Unit” field in the EDMG-Header-A         equal to 0;     -   b) The “Beam Tracking Request” field in the L-Header equal to 0         and the “EDMG Beam Tracking Request” field in the EDMG-Header-A         equal to 1; and     -   c) The “EDMG TRN Length” in the EDMG-Header-A equal to the         number of requested TRN-Units, which shall be greater than zero.

2. The beam tracking responder may:

-   -   a) Send an EDMG BRP-RX packet to the beam tracking initiator         with the number of TRN-Units requested by the beam tracking         initiator. This may correspond to a receive beam tracking         procedure.     -   b) Send an EDMG BRP-RX/TX packet to the beam tracking initiator.         In this case:         -   i. The value in the “RX TRN-Units per Each TX TRN-Unit”             field in the EDMG-Header-A of the EDMG BRP-RX/TX packet sent             by the beam tracking responder shall be equal to the value             in the “EDMG TRN Length” field in the EDMG-Header-A of the             BRP frame sent by the beam tracking initiator to start the             process.         -   ii. The value of the “EDMG Beam Tracking Request” field in             the EDMG-Header-A of the EDMG BRP-RX/TX packet sent by the             beam tracking responder may be equal to 0 or 1.         -   iii. The value of the “Beam Tracking Request” field in the             L-Header of the EDMG BRP-RX/TX packet sent by the beam             tracking responder may be equal to 0 or 1.

3. The beam tracking initiator then sends feedback to the beam tracking responder, for example, based on the transmit tracking measurements it made on the EDMG BRP-RX/TX packet from the beam tracking responder.

-   -   a) The beam tracking initiator may append the feedback to any         packet from the initiator to the responder.     -   b) The feedback type shall be the same as the feedback type in         the last BRP frame that was transmitted from the responder to         the initiator with TX-TRN-REQ equal to 1. If the initiator has         never received a BRP frame from the responder with TX-TRN-REQ         equal to 1, the initiator shall respond with all subfields of         the FBCK-TYPE field equal to 0 and set the BS-FBCK field to the         AWV feedback ID corresponding to the TRN subfields transmitted         with the same AWV that were received with the best quality.
